Buying advice for a coffee machine

[Hello
, I just discovered this forum and I would need your advice for the purchase of a grain machine.
I currently have a Saeco Odea Go for a good ten years. It is perfectly functional and I am overall satisfied with it except on one point: maintenance. Every time, you have to spend 15 to 20 minutes to clean everything, there is coffee everywhere. The water container is always full. The tank is always empty. I think it is really not practical.

I would like to change it. My specifications:
- it must make a good coffee (it's still the base)
- I want to use coffee beans-
[B]it must be super practical to clean






and if it can be done almost by itself, it's even better-
it must be easy to use.
Do you have a reference brand ? brands to avoid ?
My ideal budget 400-500 - My favorite budget 800-900Thanks
in advance for your advice
